Bryan, I use the DX Engineering RTR-1 Receive Antenna Interface with my
old TS-820S and it works great.  I use the PTT line to control the
RTR-1.  It has very fast switching and a very convenient front panel
toggle switch to manually switch between RX and TX antennas.  It is
built like a tank and will handle 200 watts.  I highly recommend it.
